Measuring the Effect of Simulated Engine Faults on the Emissions of Mechanically- and Electronically-Controlled Diesel Engines

Abstract

The gaseous and particulate emissions from two diesel engines were measured while operating under simulated fault conditions in a controlled laboratory environment. The engines were representative of those typically used in light and heavy-duty mobile underground mining equipment. Faults were applied singly and in combination. Emissions data were measured using laboratory and field instruments for comparison. The development of protocols for field-testing of vehicles are discussed.
